Advantages of LED plant lighting
2013年5月29日 コンピュータIn recent years, the global daylight reduces gradually. For example, the recent daylight in Taiwan is the shortest in 61 years.
Daylight decrease is a disadvantage for agricultural development. As the production technology progresses and people’s requirements about suppliers from china to improve plant output and shorten planting period become urgent, artificial light sources start to be adopted in plant cultivation field.
Artificial sunshine to make miracles
Based on research, many plants need red and blue light in their growth. The LED can emit light of various wavelengths. Researchers enable plants to receive "artificial sunshine" within certain wavelength range, for example, only blue and red light for 24 hours a day in the 200 square "plant factory". Thus, plants can photosyn the size even at night. products in china
In such an environment, the growth speed of plants is promoted considerably. After LED plant lighting is used, vegetables, whose normal growth period is 52 to 60 days, mature within 20 days.
Replacing sunshine with LED lights increases the cost, but the profit for peasants is not reduced. In the lab, plants are cultivated at 2 to 5 layers and LED lights are installed at each layer. In this mode, the output is independent of the weather and therefore is sharply improved.
Compared with the traditional lighting, LED plant lighting is efficient and energy-saving. For example, the light compensation experiment, conducted in a greenhouse in Holland, shows that the LED light can save 50% to 80 energy compared with the traditional high pressure sodium lamp and metal halid lamp. In a plant factory, the traditional light source needs 0.5 kilowatt per square meter; while the LED needs only 0.27 kilowatt. The total tissue culture area covers over 20 million square meters in China. If the tissue culture lighting time is 16 hours per day and 300 days per year, the fluorescent lamp consumes total 107.5 billion kilowatt hours of electricity, whereas the LED consumes 51.8 billion kilowatt hours, that is, 56 billion kilowatt hours of electricity is saved annually.
In plant cultivation, the LED light source of specified wavelength can be used to prevent agricultural insects and meanwhile minimize pesticide usage. In animal breeding, the LED light source of specified wavelength can be used to promote animals’ growth and meanwhile reduce the usage of feed additive and hormone. In ocean fishery, the LED light source of specified wavelength can be used to attract sea products and improve the catch. In microbiology, the LED light source of specified wavelength can be used to improve microorganism multiplication and implement microorganism reaction process with high efficiency and intensive output.
